COIN-FREEI) DELIVERY APPARATUS.

Specification of Letters Patent.

Patented Feb. 10, 1920.

' Z '0 all whom it may concern:

Be it known that we, GEORGE STIRLING KARoK, of 20 Fenchurch street,London, E. C., England, director, and SYDNEY HERBERT VARNDELL, of 50Rutland Gardens, Harringay, London, N. 4, England, engineer, subjects ofthe King of Great Britaln and Ireland, have invented certain new and useful Improvements in or Relating to Coin- Freed Delivery Apparatus, ofwhich the following is a speci cation.

This invention relates to coin freed clelivery apparatus for deliveringtowels and other articles of the type'in which shelves are disposed oneabove the other and adapted to be released one at a time commencing withthe bottom shelf by the angular movement of a vertical memberwhich isadapted to be operated by a coin freed mechanism. The object ofthis'invention is to provide an improved apparatus of this type.Apparatus made in accordance with this invention is characterized inthat the releasing mechanism for each shelf forms a self contained unit,comprising a plate, a pivoted supporting lever on said plate, a springpressed trip lever adapted to hold up one end of the supporting lever,an arm pivoted on said trip lever, ,asliding striker mounted on saidplate, means for putting. said arm automatically in an operativeposition with respect to said striker one. by one as the mechanism belowis operated.

Referring to the drawings filed herewith Figures 1 and'l together formaside elevation of a vending machine embodying this invention, andadapted for use in delivering towels.

Fig. 2 is a sectional plan;

Figs. 3, 3 and 3 together form a front elevation I Fig. 4 is anelevation of two units of the shelf supporting and releasing mechanism,the lower mechanism being in 'an operative position, and the uppermechanism in an inoperative position;

Fig. 5 is a similar view to Fig. 4: showing the lower mechanism after ithas been released and the upper mechanism in an operative position Fig.6 is an elevation of the inclosing cas- I Fig. 7 is a horizontal sectionof the inclosing casing, on line 1313 of Fig. 13.

a. is a main frame, 6 b b are shelves pivotally mounted on bars 0 0 0Below each shelf are supporting frames d 01 d pivotally mounted on thebars 0 0 c Mounted. on the main frame are a series of shelf releasingmechanisms, each forminoa self contained unit comprising a plate 6 e 0?.Describing thebottom one, on the plate 6 (see Fig. 4.) is pivoted asupporting lever f provided with a pointed end g and a pin it. Thesupporting lever f has a short inner member j. (See Fig. 2). On theplate 6 is a sliding striker k provided with a stud m at one end and afoot 71 at the other end. On the plate e is a pivoted trip lever 0 heldin its normal position by a spring 19. To the lever 0 is pivoted an arm9 adapted when in its lowest position to engage the foot 0?. of thestriker 7c. The arms g 9 but not the arm Q are each provi-ded with asupporting finger r r adapted to rest on the short members j y' on thelevers f 7. Lips on the levers of 0 0 support the ends of the levers f f7.

The armsg g g each pass through corresponding slots in flanges s s s inthe plates 0 e 0 whereby the angular movement of each arm is limited,the lowest position insuring engagement with the feet 01/ n n. Theplates 6 e e are also provided with lugs t t t which determine thenormal positions of the levers 0 0 0 On the main frame a is mounted avertical rocking spindle '0 provided with a trough shaped bar w (seeFig. 2) adapted to engage the studs m m m on the strikers is 70 70 Thespindle 1) is provided with bearings w w? w supported on the frame a. Atthe base of the spindle o is a lever 90 for connecting with operatingmechanism. The trough shaped bar w is held in its normal position by aspring 3 (See Fig. 1

In use assuming all the shelves 6 b b to be in their raised position,the arm 9- is in engagement with the foot n of the striker is (Fig.4:),so that when the rocking spindle e is operated the striker 7c pushesthe arm 9 moving the lever 0 so that it no longer supports the arm fwhereupon the lever f falls allowing the supporting frame tfiland shelf6 (Figs. 3, 3 and 3) also to On the main frame a of the machine ismounted a bracket 2 provided with bearings 3 and 4 adapted to support arod 5 provided with a handle 6.

In use when the operating mechanism. has

been released by means of a coin, the action of drawing out the handle6, moves the rockingspindle r and operates all the strikers 7c h Thefoot n of the, striker 70 contacts with the 'arm 9 and the latter movesthe trip lever 0. This releases the lowermost shelf, and permits the armg to fall into position for the next operation.

When the handle has been drawn out to the full. extent the pawl 3 haspassed. over theteeth 7 of the rack on the rod 5 and the lip 30 of thebell crank lever 29 passes to the; end of the flange 24 of the lever 23and is pulled into its normal position by the spring y, operatingthrough the rocking spindle a, lever m and. links 32.

On. the operator releasmg the handle 6, the rod 5 is retracted by thespring 20;

The mechanism for raising; the shelves-t0 their horizontal; positioncomprises a rack 33 adapted to engage toothed segments 34 34 34 mountedon the supportingbars c" 0 c The quadrants. are. provided with flanges35 (see Fig. 2) adapted to engage the levers i f f. The rack 33 isadapted toberaised by a handle 36,.througha. link 37 and lever-38pivoted to the frame at 39, the. end of the lever 38-being provided with'aslot39 to engage a pin 40 on the rack 33. On lifting the handle 3.6all the-levers f f f areraised to engage thelips 41" 41 of the lever 00. 0 and are supported thereby, the corresponding supporting frames d CFand (Z andshelves b b and 3 being raised and supported thereby.

.Themechanism for closingthe coinchute when all. the shelves-have been.released comprisesea. rod-41 supported on the main frame a and. providedwith. a bent end 42 which rests upon the top. lever f (see Fig. 1). Onthelower end of the rod 41 is a, tappet 43 which is adapted to strike abent lever 44 pivoted to. the frame a, so that when the lever f fallstherod 41 falls, causing the tappet. 43 to strike the lever 44 so that itsend45 enters a hole 46 (see Fig. l) in the chute47 and. prevents a coinbeing placed in the machine.

Means may be provided sothatthetowels can be delivered from the, machinein a po-. sition ready for use but connected so that they cannot bereadily removed by unauthorized. persons, such a means comprises a bentrod. 48 adapted to be placed on the frame of. the machine'but to liewithin an inclosing'casing. The lower end of the rod is heldfirmly in asocket 49 on the frame of the machine and, the end is sprung intoa clip.50 also-on, the frame a. Each towel is provided with eyelets throughwhich a chain 51 provided. with, rings 52 is passed. The chain, afterbeing passed through the eyelet is, placed on the rod 48 and the towelsare placed on the shelves. The frame a is provided with an inclinedbottom 53 to allow side. casing 55 incloses the whole apparatus I andisprovided with a hole 56 to enable the handle to be reached by theoperator and a slot 57 at the bottom to allow the towel to fall out anda slot 58- for the coin. to enter the chute.

Although the machinehasxbeen more particularly described with referenceto delivering towelsit can. be used. for other purposes...

What we; claim and desire to secure; by Letters Patent.is=:

1. Apparatus for tlelivering towels or other articles, comprising; aframe, a coin freed mechanism on; said frame, hinged; shelves disposed.one. above the other on. said frame, means for supporting said. shelves,means for releasing, said shelves. one at," a
